OK. Thanks for the clarification.

Adding '[0]' to your input image name returns the PSD composite image. It does not include an alpha channel. Remove the '[0]' and you get the image layer which does include the alpha channel: convert input.psd output.tif identify -verbose output.tif | grep -i Alpha: Alpha: 1-bit The output.tiff has...

Sorry, I do not understand. Why is the -type bilevel "escaping" from within the parentheses so as to affect the input tricolor image? Settings have been know to "escape" in IM 6, but is not the output color type supposed to come from the first image in the command line, which is ...

Not that I know about. I do not know of any other software that will read either.

Perhaps you need to install Ghostscript or if installed, Imagick cannot find it. That can happen and the delegates.xml file may need to have the full path to gs included.

TIFF and MIFF and MPC also support HDRI. With TIFF and MIFF, you need to add -define quantum:format=floating-point

One can also use connected components processing to remove small regions that may not be part of the text on the receipt. See https://imagemagick.org/script/connected-components.php

Please always provide your ImageMagick version and platform when asking questions. Also which API you are using.

You can use Deep Learning to train your data base on the fixed set of categories. Then use it to match new images. See books on Deep Learning or some forums such as https://www.pyimagesearch.com, https://www.learnopencv.com. See also OpenCV Deep learning tools. And https://opencv.org/courses/ and ht...

This works for me with test1 and test3. I did not check test2. I added a second color for the other color in the yellow border region that is more whitish. I also increased the fuzz value to 15% and replace -morphology close with connected components processing to remove small regions in the outside...

I believe the messages are saying that it has cropped the image to nothing. Your third image does not conform to the assumptions that you have a full rectangular frame about the region you want to crop. You may have to adjust the rgb color and the fuzz value to customize for each image. To trim 10 p...

Note that Unix syntax is different from Windows syntax in that regard.

I tried to blur your receipt and increase contrast and threshold, but could not get a good separation into two parts. Low contrast is very hard for separating text. I have no good solution at this time.

Your version of ImageMagick is Q16 HDRI. So it should write data outside the quantum range, if the output format supports that. Have you tried Q32 IM 7 with HDRI?

I am unaware whether IM can write 32-bit single channel PSD images. One of the developers will need to comment.

Your syntax is wrong. There is no \ for end of line in Windows. It is ^. Your second part has no input. So either remove the \ and test.jpg to read convert -density 200 test.pdf -crop 1385x690+50+0 -quality 100 output.jpg or two lines with end of line ^ character convert -density 200 test.pdf -quali...
